Quick Fixes to Try First

Before detailed troubleshooting, try these quick fixes that resolve most HP printing problems:

1. Power Cycle the Printer

A restart clears most temporary errors and resets the printer:

Press the power button to turn OFF the printer
Unplug the power cord from the wall outlet (not just the printer)
Wait 60 seconds (this clears the printer's memory)
Plug the power cord back in
Turn the printer ON and wait for it to fully initialize
Try printing again

2. Cancel Stuck Print Jobs

A stuck print job can block all new printing:

Click the printer icon in the system tray (Windows) or menu bar (Mac)
Open the print queue for your HP printer
Click "Printer" menu > "Cancel All Documents"
If jobs won't cancel, restart the Print Spooler service
Try printing a simple test page

3. Run HP Print and Scan Doctor

HP's free diagnostic tool automatically fixes common issues:

Go to hp.com/go/tools
Download "HP Print and Scan Doctor"
Run the tool and select your printer
Click "Fix Printing" and follow the prompts
The tool will diagnose and fix many issues automatically

This tool can fix: Offline errors, driver issues, print queue problems, port configuration, and more.

4. Set HP as Default Printer

Ensure your computer sends jobs to the right printer:

Windows 10/11:

Open Settings > Devices > Printers & Scanners
Turn OFF "Let Windows manage my default printer"
Click your HP printer, then click "Manage"
Click "Set as default"

Diagnose Your Problem

Different symptoms require different solutions. Identify your issue:

Fix Offline Errors

Your computer shows the HP printer as "Offline" even though it's turned on. This is one of the most common HP printer issues:

Windows: Set Printer Online

Open Settings > Devices > Printers & Scanners
Click on your HP printer
Click "Open print queue"
Click "Printer" menu at the top
Uncheck "Use Printer Offline" if it's checked
Also uncheck "Pause Printing" if checked

Restart Print Spooler Service

This often fixes persistent offline issues:

Press Windows + R, type services.msc, press Enter
Find "Print Spooler" in the list
Right-click and select "Restart"
Close Services and try printing again

Command line method: Open Command Prompt as Administrator and run: net stop spooler && net start spooler

Check Port Configuration

Incorrect port settings can cause offline errors:

Open Control Panel > Devices and Printers
Right-click your HP printer > Printer Properties
Go to "Ports" tab
Ensure the correct port is checked (usually WSD or Standard TCP/IP Port)
For network printers: Click "Configure Port" and verify IP address matches printer

Use HP Print and Scan Doctor

HP's diagnostic tool is specifically designed to fix offline issues:

Download HP Print and Scan Doctor from hp.com
Run the tool and select your printer
Click "Fix Printing"
The tool will automatically diagnose and fix the issue

Fix Connection Issues

USB Connection Problems

If your HP printer connects via USB:

Try a different USB port: Use a port directly on the computer, not a hub
Try a different cable: USB cables can fail or be incompatible
Check cable length: Cables over 6 feet can cause issues
Reinstall driver: Unplug printer, uninstall driver, reconnect to reinstall

WiFi Connection Problems

Check WiFi Status on Printer

Look for the WiFi icon on the printer display or control panel
Blue solid light = connected; blinking = attempting to connect; off = not connected
Print a Wireless Network Test Report from the printer menu

WPS One-Button Setup (Easiest)

Press the WPS button on your router
Within 2 minutes, press and hold the Wireless button on your HP printer
Wait for the WiFi light to become solid
This bypasses manual password entry

Manual WiFi Setup

On the printer: Settings > Network > Wireless Setup Wizard
Select your WiFi network name (SSID)
Enter the WiFi password carefully (case-sensitive)
Wait for connection confirmation

WiFi Direct (No Router Needed)

Connect directly to the printer without going through your router:

Enable WiFi Direct on printer: Settings > Network > WiFi Direct
On your phone/computer, look for network named "DIRECT-xx-HP..."
Connect using the password shown on printer
Print through HP Smart app or directly

Common WiFi Issues

2.4GHz vs 5GHz: Most HP printers only support 2.4GHz networks. Check your router settings.
IP address changed: If your router assigned a new IP, you may need to reconfigure or use HP Smart to reconnect
Firewall blocking: Temporarily disable firewall to test if it's blocking the printer
Too far from router: Move printer closer or add a WiFi extender
Too many devices: Some routers limit connected devices - try disconnecting others to test

Ink Cartridge Problems

HP printers are sensitive to cartridge issues. Here's how to troubleshoot:

"Cartridge Problem" or "Cartridge Not Recognized"

Remove and reseat: Take out the cartridge and reinstall it firmly until it clicks
Clean contacts: Wipe the copper contacts on the cartridge with a lint-free cloth
Also clean printer contacts: Gently clean the contacts inside the printer carriage
Check protective tape: New cartridges have orange or yellow tape - ensure it's fully removed
Check expiration: HP cartridges have expiration dates - old cartridges may not work
Try a different cartridge: If one cartridge consistently fails, it may be defective

"Low Ink" Warning But Cartridge Is New

Reset the cartridge: Remove it, wait 10 seconds, reinstall
Check if it's HP genuine: Third-party cartridges may not report levels correctly
Firmware update: Some HP updates affect cartridge recognition
Continue printing: HP often allows you to override low ink warnings

HP Instant Ink Issues

HP Instant Ink cartridges work differently from regular cartridges:

Subscription required: Instant Ink cartridges only work with an active subscription
Page limit reached: If you exceed your plan's pages, printing may stop until next billing cycle or you upgrade
Payment issue: Verify your payment method is current in your HP account
Can't use regular cartridges: While enrolled, you must use Instant Ink cartridges
To switch back: Cancel subscription, wait for service to end, then use regular HP cartridges

Third-Party Cartridge Issues

HP printers may display warnings with non-HP cartridges
Some HP firmware updates block third-party cartridges
You can usually click through warnings to continue printing
Print quality may vary with third-party ink
HP's warranty doesn't cover damage from third-party cartridges

Print Head Cleaning

Clogged print heads cause blank pages, missing colors, and streaky prints. HP inkjet printers need regular maintenance:

Automatic Print Head Cleaning

From HP Smart app: Open app > Your printer > Print Quality Tools > Clean Printhead
From printer panel: Settings > Tools > Clean Printhead (or Printer Maintenance > Clean)
From Windows: Devices and Printers > Right-click HP printer > Printing Preferences > Maintenance tab
Run Level 1 cleaning first, then print a test page
If needed, run Level 2 (deeper cleaning) - uses more ink
Wait 30 minutes between cleaning cycles

Print a Quality Diagnostic Report

Access: Settings > Reports > Print Quality Report (or similar)
Examine the printed pattern for gaps, streaks, or missing colors
This helps identify which colors or areas are affected
Run cleaning for specific colors if available

Print Head Alignment

Misalignment causes blurry text and color fringing:

Access: Settings > Tools > Align Printhead (or Print Quality > Alignment)
The printer will print an alignment page
For manual alignment: select the best-looking pattern from each set
For automatic: place the page on scanner glass and let printer read it

If Cleaning Doesn't Help

Check ink levels: Very low ink prevents proper cleaning
Replace cartridges: Old or dried cartridges may have damaged heads
Wait and retry: Let the printer sit overnight, then try cleaning again
HP printers with integrated heads: Replacing the cartridge replaces the print head
HP printers with separate heads: The print head assembly may need replacement (expensive)

DeskJet Specific Issues

HP DeskJet printers are popular home printers with some model-specific considerations:

Common DeskJet Problems

Cartridge carriage stuck: Power off, open access door, gently move carriage to center, remove obstructions
Paper feed issues: Clean pickup rollers with lint-free cloth dampened with water
Printing very slowly: Check print quality setting - "Best" mode is much slower than "Normal"
"E" error on display: Each number indicates a specific issue (see error codes section)

DeskJet Cartridge Types

Standard cartridges: HP 63, 65, 67, etc. - print head is integrated into cartridge
XL cartridges: Same fit, more ink, better value for frequent printing
Setup cartridges: Included with new printer, have less ink than standard
Instant Ink cartridges: Subscription-based, won't work without active plan

OfficeJet Specific Issues

Common OfficeJet Problems

Scanner unit not closing: Check for paper or obstructions under the lid
ADF (Document Feeder) jams: Clean ADF rollers, fan paper before loading
Fax not working: Verify phone line connection, check fax settings match your line type
Copy function works but print doesn't: Issue is with computer connection, not printer

OfficeJet Pro Features

PageWide technology: Some OfficeJet Pro models - stationary print head, very fast
Ethernet connection: More reliable than WiFi for office environments
Automatic duplex: Check duplex unit is properly installed if two-sided printing fails
Multiple paper trays: Verify correct tray is selected in print settings

LaserJet Specific Issues

HP LaserJet printers use toner instead of ink and have different troubleshooting needs:

Toner Cartridge Issues

Shake the toner: Remove cartridge, shake gently side-to-side 5-6 times, reinstall
Remove protective seal: New cartridges have a pull tab that must be removed completely
"Cartridge Low" warning: Can usually print several hundred more pages after this warning
Print quality declining: Shake cartridge first; if still faded, replace

Common LaserJet Problems

Blank pages: Toner seal not removed, or cartridge empty
Spots or lines on every page: Drum may be damaged or dirty - inspect and clean/replace
Paper curling: Paper is absorbing moisture - use fresh paper from sealed ream
Fuser errors: Internal heating element issue - may need service
Ghost images: Faint repeating images - usually drum or fuser issue

LaserJet Maintenance

Clean the printer: Use a dry lint-free cloth to remove toner dust from inside
Don't use compressed air: This can spread toner dust and damage components
Replace maintenance kit: High-volume printers have kits including fuser, rollers, etc.
Update firmware: Fixes bugs and improves compatibility

HP Smart App Issues

HP Smart is HP's recommended app for setup and management. Here's how to troubleshoot common issues:

"Printer Not Found" in HP Smart

Same network: Ensure phone/computer and printer are on the same WiFi network
Restart printer: Turn off, wait 30 seconds, turn back on
Force close and reopen: Completely close HP Smart and reopen it
Check Bluetooth: HP Smart uses Bluetooth for initial setup - enable it
Try adding manually: Use the printer's IP address to add it

HP Smart Shows "Offline"

Force close HP Smart app completely
Restart the printer
Check WiFi signal strength at printer location
Reopen HP Smart and wait for it to reconnect
If still offline, remove printer from app and re-add it

HP Smart Won't Install or Update

Windows: Get HP Smart from Microsoft Store, not HP's website
Mac: Get HP Smart from App Store
iOS/Android: Ensure device OS is up to date
Storage space: Free up space if installation fails
Clear app cache: If updating fails, try uninstalling and reinstalling

Can't Print from HP Smart

Ensure printer is online in the app (not showing offline)
Check ink levels in the app
Verify paper is loaded correctly
Try printing a test page from within the app
Update both the app and printer firmware

Frequently Asked Questions

Why does my HP printer say offline when it's turned on?

This usually means Windows can't communicate with the printer. Run HP Print and Scan Doctor to fix it automatically. Otherwise: restart the Print Spooler service, check "Use Printer Offline" is unchecked in print queue, verify your connection (USB or WiFi), and ensure the correct printer port is selected.

Why won't my HP printer print black?

Common causes: 1) Black cartridge is empty or dried out, 2) Print head nozzles are clogged - run cleaning cycle, 3) Protective tape still on new cartridge, 4) Cartridge contacts need cleaning. Try removing and reseating the black cartridge, cleaning the contacts, and running a print head cleaning.

How do I reset my HP printer to factory settings?

Access varies by model: Usually Settings > Printer Maintenance > Restore > Restore Factory Defaults. For printers without screens, hold the Cancel and Wireless buttons for 5 seconds. Note: This erases WiFi settings and custom preferences.

Can I use non-HP ink cartridges?

Third-party cartridges physically work in most HP printers, but HP may show warnings. Recent firmware updates have made some third-party cartridges incompatible. Using non-HP ink may void warranty coverage for damage caused by the cartridges. Many users successfully use third-party ink, but results vary.

Why is my HP printer printing so slowly?

Check your print quality setting - "Best" mode is much slower than "Normal." Also: high-resolution images print slower, WiFi is slower than USB, and complex documents with many graphics take longer. For faster printing, use "Draft" or "Normal" quality when possible.

How do I connect my HP printer to WiFi without the app?

Use the printer's control panel: Settings > Network > Wireless Setup Wizard. Select your network and enter the password. Or use WPS: Press the WPS button on your router, then press and hold the Wireless button on your HP printer within 2 minutes.

What do I do if HP Print and Scan Doctor doesn't fix the problem?

If the diagnostic tool can't fix it: 1) Completely uninstall and reinstall HP software, 2) Try a different connection method (USB vs WiFi), 3) Test printing from a different computer or phone, 4) Contact HP Support with the specific error code or issue description.
